Material
SCH20 / GG20 gray cast iron
Gray cast iron for machined parts, repair blanks, bushings, pulleys, covers, supports and general engineering components.
| Grade | Properties | Typical use | Possible reference |
|---|---|---|---|
| SCH20 | Good machinability, vibration damping, stable casting structure | Bushings, covers, pulleys, flanges, supports | GG20 / EN-GJL-200 by agreement |
| SCH15 | Softer gray cast iron for low-loaded parts | Light covers, spacers, simple sleeves | GG15 by agreement |
| SCH25 | Higher strength gray cast iron | Machine parts, housings, loaded covers | GG25 by agreement |
| SCH30 | Higher mechanical load capability | More demanding machined parts and supports | GG30 by agreement |
Where SCH20 is used
SCH20 is chosen when a part should be easy to machine and should damp vibration better than many steels. It is a practical material for short round billets, repair parts and custom machined components.
For export requests please specify the required standard, drawing tolerances, diameter, length, quantity and whether SCH20 must be matched to GG20 / EN-GJL-200 in your purchasing documents.
